"If you already have a PC with Media Center Edition installed you will be able to upgrade to Windows XP Media Center Edition 2004 via Windows XP Service Pack 2 (SP2) once it is released. By installing the Windows XP Media Center Edition 2004 upgrade as part of SP2, you will also be able to take advantage of the security enhancements included in this service pack. SP2 is scheduled to be released in the first half of this year."
This appears to be great news, and much relief for the MCE 2002 users that still haven't received their free MCE 2004 upgrade from their OEM. BTW, if you are interested in the new features of MCE 2004, click
